Microsoft is losing yet another long time employee, Antoine Leblond, who was a major force behind the company's Office division and later for the development of Windows 8. Re/code reports that Leblond sent out an email to team members late on Friday announcing his departure from Microsoft after nearly 25 years.

Every single day I have had here has been amazing in its own way, and I will never look back on all of these years with anything but fondness, pride in what we’ve accomplished together, and a real appreciation for having been lucky enough to be part of so many awesome things I am sad to leave all of you, but also incredibly excited for what comes next.

Leblond spent the majority of his time at Microsoft in the Office division but the last five years he was the the corporate vice president of Windows. Working under Steven Sinofsky, Leblond was in charge of the cloud services portion of Windows 8, including its Windows Store feature.
